ni e END WEIGHT SUPPORTS AND CONTROLS FOR smcusc MACHINES Filed Mar. 18,1959, Set. 0. 800,336 10 Claims. 01. 140-102 This invention relates toend weights in general for slicing machines and more particularly to anend weight supports and controls for a chute that is inclined to thevertical but otherwise substantially vertical to the path of movement ofthe knife blade of a slicing machine.

Airiong the objects of the present invention it is aimed to provide animproved end weight support the lower end of which will just clear theknife blade when in position to engage the article to be sliced andwhich will positively clear the knife guard when swung into inoperativeposition.

It is still another object of the present invention to provide an endweight support the lower end of which will just clear the knife bladewhen in position to engage the article to be sliced and which will notonly positively clear the knife guard when swung into operative positionbut will also clear the chute supporting bracket when swung into itsfinally locked inoperative position.

These and other features, capabilities, and advantages of the presentinvention will appear from the subjoined detailed description of onespecific embodiment thereof illustrated in the accompanying drawings inwhich:

Fig. 1 is a perspective of a slicing machine equipped with the improvedend weight control in operative position.

Fig. 2 is a fragmental perspective of the slicing machine shown in Fig.1 equipped with the improved end weight support shown in finally lockedinoperative position.

In the embodiment shown there is illustrated a slicing machine such asdisclosed in United States Patent No. 2,665,531 having a main frame 1having an extension 2 provided with an opening 3 through which extendsthe arm 4 reciprocably slidablein the extension 2. The outer free end ofthe arm 4 is connected'to the conventional chute or article carrier 5having two wings 6 and 7 forming a dihedral angle with one anotherdisposed at an angle to the vertical but otherwise substantiallyvertical to the plane of the rotatable cutting knife 8 which isrotatably mounted in the gear housing 9 containing the drivingconnection between the motor 10 and the knife 8, the gear housing 9 andmotor 10 being mounted on the main frame 1.

Adjacent the knife 8 and in substantial alinement with States Patent 2the plane of the knife 8, there is disposed the gauge plate or platform11. In practice the chute 5 is reciprocated across the gauge plate 11and knife 8 into and out of cutting relation with the knife 8.

On the edge of the plate 7 disposed substantially perpendicular to theknife 8, there is formed the rod 12 mounted in the upper bearing ear 13and lower bearing ear 14 extending from such edge of the plate 7. Thelower edges of the plates 6 and 7 just clear the cutting knife 8 whenthe chute is moved across the knife 8 into cutting relation with theknife 8. There is provided a guard 15 consisting in the present instanceof an inner plate 16 disposed above the central portion of the knife 8from which extends the arcuate guard portion 17 enclosing the cuttingedge of the knife 8 along its outer arcuate path of movement. The guard.15 alsohas extending from the same the short rectangular plate portion18 adjacent the extension 2 of the frame 1. The guard 15 is connected toand supported by the driving connection, not shown, mounted in the gearhousing 9. The upper faces of the plate 16, the guard portion 17 and therectangular plate portion 18 extend slightly above the upper face of theknife 8. The lower edges of the wings 6 and 7, however, clear the upperface of the plate portion 16 in its movement across the sarne. The upperface of the guard portion 17 may, be slightly above the upper face ofthe plate portion 16 but since the chute 5 does not in its reciprocationmove over to the guard portion 17, there is of course no danger of thelower edges of the wings 6 and 7 engaging the guard portion 17. v

However, since the upper faceof the arcuate guard portion 17 may extendinto the path of movement of the pins 19 extending downwardly from thelower face of the arm 20 of the end weight, it is desirable that whenthe end weight is swung into inoperative position, that shown in Fig. 4of the drawings, it is desirous that the arm 20 be raised so that thepins 19 will. clear the guard plate portion 17 when swung from itsoperative position into its inoperative position. 'For this purpose thelower car 14, see'Figs. 3, 4, and 5 is provided with a cam face 21 tocooperate with the fibrous projection 22 at the lower end of the arm 20adjacent its cylindrical journal 23 slidably mounted on the rod 12.Above the car 14 on the rod 12 as many shims or washers 24 may beprovided, three being shown, as are necessary to position the arm 20 andtherewith the pins 19 so that they will at least clear the central guardportion 16 in operative position. When, however, it is desirous to movethe arm 20 from the operative position shown in Figs. 1 and 3, into theposition shown in Fig. 4, then due to the cooperation of the fibrous pin22 and cam face 21, the arm 20 and therewith the pins 19 will be raisedto clear the arcuate guard portion 17. Since the upper face of therectangular guard portion 18 may be disposed in a plane still higherthan the plane of the upper face of the guard portion 17, the journal23, see Figs. 1 and 7, is provided with a boss 25 which will engage thefree edge 26 of the plate 27 and obstruct the further outward movementof the arm 20 until the bearing 23 of the arm 20 clears the plate 27 andthe projection 22 rides up on the cam face 28 formed by the upper edgeof the plate 27, see Fig. 6. In order to cushion the upper movement ofthe bearing 23 relative to the ear 13, the spring 29 is provided belowthe ear 13. When the projection 22 rides along the cam face 28 the armwill be swung over, see Fig. 6 where the semi-circular projection 30clears the semi-circular projection 31 formed on the boss 32, formed onand ex tending from the arm 4, see Figs. 1, 2 and 6. The projection 30has a cam face 33 which is adapted to engage the cam face 34 of theprojection 31 so that the pro- 3 jection 30 will ride over theprojection 31 into the locking position shown in Fig. 6.

In the present invention advantage is taken of the position of the endof the wing 7 relative to the rod 12 forming the plate or extension 27on the wing 7 and forming the cam face 28 to coo erate with the fibrousprotection 22 to raise the arm 20 and clear the arm 4 before swin ingthe arm 20 back into the finally locked position with the pro ection 31as shown in Fig. 6, and also using the edge 26 of the extension 27 tocooperate with the boss 25 formed on the journal 23 of the arm 20 to barthe arm 20 from swinging around into contact with the arm 4 or incontact with the rectangular guard portion 18 and conseouentlv insurethat the arm 20 will not be swung around to the finally lockedinoperative position until the arm 20 has been raised above the cam face28, and finally using the inner upper face of the car 14 ad acent to thewing 7 and which ear is a part of the portion 35 extending from thelower edge of the pl te 7 which face constitutes the cam face 21 to beengaged by the fibrous projection or button 22, see Figs. 3 and 4 toraise the arm 20 so that its pins 19 will clear not only the rectangularguard portion 18 but also the arcuate guard portion 17.
